I just can’t find a decent email client that looks like it’s from the last 20 years. Geary and Evolution both appear to be pretty modern but something about using Gmail with a Yubikey just doesn’t work and neither of them will connect to my account. Both on Fedora and OpenSUSE. Thunderbird works but it’s so old fashioned and Betterbird doesn’t look much better. What’s everyone else using?
Interesting… Which email provider do you use?
Can you choose which folders use real-time push vs which folders use polling?
Fastmail.
I’m afraid not. I’m pretty sure the entire account uses polling. I’ll usually open the app and hit F5 to quickly poll for results, otherwise I’m waiting for the next sync.
Having said that, the unread counter works fine for sub-folders:
Edit: I was wrong, Mailspring uses the IMAP IDLE extension to wait for new mail delivery. Still doesn’t stop me from spamming F5 when I’m waiting for new mail to arrive.
The reason I was asking about the folders is that IMAP IDLE only works for one folder at a time. If you want real-time push for 10 folders (for example), it has to open 10 separate IMAP connections. Because of this, clients usually either only enable push for the inbox, or let you choose which folders to enable it for.
